Quality control for bone quality parameters affected by subject motion in high-resolution peripheral quantitative computed tomography

►Presents manual and automatic grading for motion monitoring in HR-pQCT. ►Manual grading is reproducible across and between sites with training. ►Density parameters are more robust to motion than structural and FE parameters. ►Manual grade of 3 or automatic grade of 1.2 yield acceptable reproducibility. ►Tables are provided for determining appropriate grading thresholds.
